Earl's Ano-Tuff Hard-Line AN Tube Fittings

A Couple of Twists to Be Out of a Pinch!Earl's Ano-Tuff Hard-Line AN Tube Fittings are precision machined from aluminum with a distinctive, bright dipped black, military spec hard anodizing. This recently developed hard anodizing process adds superior wear and corrosion resistance to aluminum at a reasonable price. The Ano-Tuff coating penetrates the aluminum to create a surface that lasts twice as long as traditional anodizing. Rated at 50 psi max, these fittings are used to connect the bare end of a hard tube to an AN-style fitting. Made in the USA!
